I can only use this to brew 4-10 oz cups.  No benefit over normal pods. 
I really want to be able to brew 14-16 oz cups without having to do two brews.
I also bought the Carafe, but can't use it.  This filter doesn't work with it, there is no other resuable that will work, and I CAN'T FIND THE K-CARAFE PODS IN THE GROCERY STORES AROUND ME.  So my money spent on the Carafe was wasted also.
